Devil's Smith

Sea's Tinkerings

At third level, you've mastered the art of working with sea prism and seastone-infused objects. At level 3, you gain access to the first Tier upgrade on the Seastone Infusion list. You may add the infusion to your masterwork weapon for free but to add it onto other weapons you must spend 10DT and the materials listed for each tier. Additionally, you gain access to the following Jury Rigs:

Suppression Beacon: This structure occupies a 10ft square. Devil fruit users that start their turn or move within 15 ft of the Suppression Beacon must make a Constitution Saving Throw or gain the Suppressed effect for 1d4 turns. At 11th level, the area that the suppression beacon affects is 35ft, the Constitution Saving Throw is made with a -4 to the save, and the effect lasts for 1d6+1 rounds.

 Prism of Your Own Making

At 6th level, your sea prism experimentation has allowed you the ability to create special upgrades to your armor and weapons. You gain access to special upgrades, also known as Prism Upgrades, that you may add by spending 3DT and 25k per tier of upgrade you try to add to your weapons and armor. You can only add T1 upgrades when gaining this feature but gain 1 tier higher upgrades from the Prism upgrades list every time you would gain a new subclass feature. These Prism Upgrades act like masterworks, they do not function if they were given to other people that aren’t yourself as these signify your expertise in your craft. They do however, count as upgrades for upgrade limits.

Overdrive

At 10th level, you are able to send your item into overdrive. As a bonus action, if you are wielding a seastone-enhanced weapon or armor, you may release the true essence of the stone to create a 10ft radius aura centered on the item that lasts for 1 minute. Any DF user that starts their turn in the area or moves into it for the first time on their turn must make a Constitution Saving Throw with a -2 to the save and be suppressed on a failure for 2 turns. As well, if you activate this on your armor, it gains +1 to AC and if you use a weapon for activation, it gains a +2 to attack and damage rolls. You may only use this ability twice per long rest.

Stress to Suppress

Your work with the unique stones and energies has led to you being able to activate their natures vin moments of danger. At level 14, you're able to release condensed Sea Prism in a way that either attempts to Suppress or Disrupt an enemy. A number of times equal to half your proficiency bonus(rounded up), you may try to activate the energy of your sea stone as a reaction to being hit by a Haki User or Devil Fruit user. They must make a Constitution Saving Throw versus your Special Technique Save DC becoming Suppressed or Disrupted (your choice) for 1d6+2 rounds. While affected by this feature, the Suppressed or Disrupted creature gains 1 level of Exhaustion. As well, while affected, you gain a +2 to attack and damage rolls against them.

Perfect Blend

At 18th level, You've perfected your sea-stone and sea prism use into, allowing it to function as pure ocean energy. You may now use your Overdrive feature 4 times per long rest and use Stress to Suppress and extra 2 times. As well, you’ve learned how to incapacitate the weak and strong DF users by your refined seastone construction. While applying Suppressed to a DF user, you may stack Suppressed on them though this does not increase the effects of suppression. If a DF user gains more than half of their proficiency modifier(rounded up) in suppressed stacks, they must make a Constitution Save at disadvantage against your Special DC+half your proficiency bonus(rounded down) or become incapacitated for one minute. After this ability activates, the amount of stacks of Suppressed resets to 1. Once a creature succeeds this save twice, they are considered immune to its effects for 24 hours.
